WIRE-CONNECT.

Specification of Letters Patent.

Patented June 30, 1914.

Application filed December 3, 1913. Serial No.- 804.351.

wire connectors, the object of the invention being to provide animproved coupling which is adapted to-connect the electric wires or cables permitting the coupling to be readily made without the necessity of solder or spllcing.

A further object is to provide an improved connector which comprises two members adapted to clamp a cable between them and capable of adjustment to accommodate d fferent sizes of cable and provide improved means for preventing any turning move ment of the coupling or the cable relative to each other.

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a view in elevation illustrating our improved connector coupling and main cable with a branch. Fig. 2 is a view in longitudinal section through the connector shown in Fig, 1. Fi 3 is a view in section on the line 3-3 of mentary view in elevation illustrating the hinged end of one of the coupling members.

Our improved coupling comprises two members 1 and 2, both of which at one end are curved in semi-cylindrical form as shown at 3 to inclose the cable 4. The curved end of the member 1 is bifurcated or in other words provided with parallel ears '5 for the reception of a hinge pin 6 located in openings 7 in said ears and snugly fitting said openings. The curved end of member 2 is provided with a tongue 8 which fits between the ears 5, and is provided with an elongated slot 9 through which the pin 5 pro ects. Threaded openi 10 are formed in the end of tongue 8, and in these threaded openin s, screws 11 are located and bear against e pin 6. By adjusting these screws 11, the

ig. 2,"and Fig. 4 is a fragf position of the-pin 6 in the slot 9 can be varied so that the members may snugly fit around various sizes of cable. In other words, if the coupling is to clamp around a cable larger than that shown in Fig. 2, the

screws 11 can be unscrewed the necessary' distance, so that the circular portions 3 of the members 1 and 2 will fit around the said larger cable, andby reason of these screws, a considerable adjustment is had so that the device ma accommodate itself to the cable.

The mem ers 1 and 2 at their free ends,

when together, constitute a 'conical split shank-12 which is externally screw-threaded as shown at 13- and internallg recessed as shown at 14. A branch wire or cable 15 is securely clamped in the recesses 14 when'a 2,. secure y clamping them about the cable 4, t

and also about the cable or branch 15.

To prevent any ossibility of the coupling turning on the ca 1e or vice versa, we provide a screw-threaded opening 17 in one of the members, this opening being illustrated in member 1, and locate in said threaded opening, apointed screw 18 which is screwed into engagement with the cable, the pointed inner end of said screw projecting between wires of the cable and operatin as a posi tive lock, preventing any possibi ity of independent movement,

By providing our improved construction of members, with their novel form of binge permitting adjustment of the coupling, we are enabled to utilize our improvements with equal facility on various sizes of cable and by reason of the locking screw 18, we can securely lock the parts together so that the electrical connection will be maintained as perfect] after a period of time as when first ma e. With couplings where the parts are capable of moving, the electrical connection becomes more or less defective, but by providing a positive locking screw, this is absolutely overcome.

Various slight changes might be made in the general form and arrangement of parts described without de artin from our inven; tion, and hence we 0 not imit ourselves to the precise details set forth, but consider ourselves at liberty to make such chan and alterations as fairly fall within t e spirit and scope of the appended claims.

sisting of two members, said members .hav-

ing curved portions adapted to be positioned around a cabl? a hinge pin connecting the curved ends 0 said members, one of said members having a slot in which the 'pin is located, a screw in the said slotted member engaging the ,pin and permitting adjustment of the pin in the slot, the free ends of said members externally screw-threaded and of general conical form when together, and a conical nut screwed onto said threaded ends, substantially as described.

2. A connector comprising a clamp consisting of two members, said members having curved portions adapted to be positioned around a'cable, a hinge pin connecting the curved ends of said members, one of said members having-a slot in which the pin is located, a screw in the said. slotted member engaging the pin and permitting adjustment of thepin in the slot, the free ends of said members externally screw-threaded and of general conical form when together, a conical 'nut screwed onto said threaded ends, one of said members at its curved portion havicense ing a tongue located between said ears, said ears having circular pin receiving openings, said tongue having a pm receiving slot, a

.pin located in said openings and slot, screws in the tongue engaging the in and limiting the movement of the pin 1n the slot, the free ends of said members externally screwtreaded and internally recessed, and a screw' positioned on said threaded ends of the members, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses. v
